The food coloring will spread throughout the water and become homogeneous faster than it would in cold or warm water. The food coloring would also mix evenly with the water faster if you stirred the water after adding the food coloring.
This happens because the molecules are moving faster when they are heated up stirred.
it evaporates
What happen to the soil and water when they are heated? http://wiki.answers.com/FAQ/2455http://wiki.answers.com/FAQ/2502
for an example:I added food coloring to the water to make it look pink
Dyes or colorings are added to water bases.
yes
The water evaporates
The water will turn into whatever color the food dye.
It will get warmer.
It loses its water content and becomes brown.
Physical because we can still seperate the particles
salt water
the food coloring slowly moves around in the glass (like smoke would) and that is happening because the particles in the food coloring are not use to the temperature of the water,but as the particles get use to the temperature they move a little faster and spread everywhere in the water. Slowly disperse throughout the water, this is because of diffusion.
